Abstract

The invention discloses an anti-static polyvinyl alcohol fruit and vegetable fresh-keeping film. The anti-static polyvinyl alcohol fruit and vegetable fresh-keeping film is characterized by being prepared from the following raw materials: appropriate amounts of camellia seed, mint leaf, rhizoma zingiberis, pine twig, clove, acetone, anhydrous sodium sulfate, zeolite, sodium nitrate solution, silver nitrate solution, sodium hexametaphosphate, hydroxyethyl acrylate, acrylic acid, absolute ethyl alcohol, azodiisobutyronitrile, lauryl mercaptan, polyvinyl alcohol, vinyl acetate, ammonium persulfate solution, octadecyl imidazoline, fatty alcohol-polyoxyethylene ether, dodecyl potassium phosphate, and deionized water. The anti-static polyvinyl alcohol fruit and vegetable fresh-keeping film of the invention is good in mechanical performance, stable in structure, good in air permeability, and good in antibacterial action, and can slow down endogenous metabolism aging of fruits and vegetables and spoilage caused by exogenous microorganisms, thus greatly prolonging the length for preservation and effectively keeping the quality of the fruits and vegetables.

Description

technical field [0001] The invention belongs to the field of materials and agriculture, and in particular relates to an antistatic polyvinyl alcohol fresh-keeping film for fruits and vegetables and a preparation method thereof. Background technique [0002] At present, the storage and preservation methods of fruits and vegetables mainly include low-temperature refrigeration, controlled atmosphere, irradiation, chemical sterilization and plastic wrap packaging. Among them, the fresh-keeping film method is widely used due to its low cost, simple operation, wide application range and obvious effect. The currently used plastic wraps mainly include ordinary plastic wraps, microporous plastic wraps, anti-fog functional plastic wraps, edible plastic wraps and antibacterial plastic wraps. Due to the different fresh-keeping requirements of various fruits and vegetables, a single-function fresh-keeping film cannot meet the requirements. Therefore, it is necessary to develop multi-fun...
